That's sad, and one reason I don't like hitting the face of someone if I happen to get into a fight with them.
The whole reason this started was probably from a mouthy player talking down to a fighter...not a good thing.
I remember getting belligerent with a martial arts fighter in a bar when I was young (didn't know what he was since he looked normal to me) and ended up with his kung fu grip on my neck...
Needless to say, I learned my lesson that day.
